Where is my phone??????

Dropped my phone off for repairs on the 30th of April 2019 at the Canal Walk branch in Cape Town. Went back 3 weeks later to inquire regarding the status of the repair. Initially I was informed that the repair process would take roughly 3 weeks. The employee that I dealt told me he could see on the system that the phone has been received at the repair center and that he would follow up with the center and get back to me the next day. As you can guess that never happened. I went back the week thereafter only for same said employee to tell me that the repair center has not come back to him yet, and therefore he has not informed me yet. He could have called at least and informed me of this. It is now going into the 6th week and I still haven't heard anything. Firstly MTN, teach your employees never to over promise and under deliver, it reflects really badly, and makes you look ***********. Secondly, where the hell is my phone and how long is it still going to take???????!!!!!!!!!!!!!!!!!!!!! I have been a loyal customer for many years and at this point I will cancel my contract and move to a competitor in the blink of an eye. So contact me asap. if you want to retain a customer.
